About Graphics...

Have been investigating my new computer and there is one thing I have not had before so dont know what its for or how to use it...I have Intel Graphics Media Driver, when I click onto it Graphic options comes up, then Graphic Properties. On this it says..Intel(R) 82915G/GV/910GL Express Chipset Family Prop;I have looked at the different options there and one of them says to download the Driver go to such a place, but there I dont know what to download to be safe, would appreciate some advice and explanation on what I have got here please, thanks in advance,
